Remove the plastic cover at the bottom of the mouse

Do not do this! There are three clips under the mouse, you just need to move them gently out of the way. Two are available when the battery cover is removed, the third is accessible after you remove the battery.

Frying the darker plastic cover open without damaging it is near impossible. I have a problem with my mouse wheel and I don't know how to lubricate it or fix the sensor. Can someone help with that?

These are bad instructions, the top is released with 3 clips accessible under the battery cover, prising it off from above will break those clips. It can be hard to work out where the clips are and how to release them, but there are 3 one on each side and on under the battery. Aside from that the only other retention is a couple of hooks on the mouse buttons.

Agree that prizing the top off like this is going to damage it! Maybe my mouse, being blue on top, and black on bottom made this easier to spot, but it was very easy for me to see the three clips on the bottom. Hopefully anyone who wants to open theirs will see your comment and not use the opening tool like this.
